 # siibraLab - a MATLAB toolbox for working with brain atlases using the siibra toolsuite

 ``siibra`` is a toolsuite for working with brain atlases that integrate parcellations and reference spaces at different spatial scales, covering multiple aspects of brain organization, and linking features from different data modalitites to brain structures. It aims to facilitate the programmatic and reproducible incorporation of brain region features from different sources into reproducible neuroscience workflows.  siibraLab is a Matlab® toolbox for accessing functions provided in siibra. 
 
 siibra provides structured acccess to parcellation schemes in different brain reference spaces, including volumetric reference templates at both macroscopic and microscopic resolutions as well as surface representations. It supports both discretely labelled and continuous (probabilistic) parcellation maps, which can be used to assign brain regions to spatial locations and image signals, to retrieve region-specific neuroscience datasets from multiple online repositories, and to sample information from high-resolution image data. Among the datasets anchored to brain regions are many different modalities from in-vivo and post mortem studies, including regional information about cell and transmitter receptor densties, structural and functional connectivity, gene expressions, and more.
